What is GitHub Actions?

GitHub Actions is a continuous integration and continuous delivery (CI/CD) tool that allows developers to automate their build, test, and deployment pipelines. It is a powerful tool that enables developers to create custom workflows that automate various tasks, such as building and testing code, deploying to production, and more. With GitHub Actions, developers can create custom workflows that are triggered by specific events, such as push, pull requests, or schedule.

Main Features of GitHub Actions

GitHub Actions has several key features that make it a powerful tool for automation and scripts. Some of the main features include:

• Workflows**: GitHub Actions allows developers to create custom workflows that automate various tasks.
• Actions**: GitHub Actions provides a range of pre-built actions that can be used to automate tasks, such as building and testing code.
• Runners**: GitHub Actions provides a range of runners that can be used to execute workflows, including Linux, Windows, and macOS.

Installation Guide

Step 1: Create a GitHub Actions Workflow File

To get started with GitHub Actions, you need to create a workflow file in your repository. This file defines the workflow and the actions that will be executed. To create a workflow file, follow these steps:

1. Create a new file in your repository’s `.github/workflows` directory.
2. Name the file `main.yml` or any other name that you prefer.
3. Add the following YAML code to the file: `name: My Workflow on: push: branches: – main jobs: build: runs-on: ubuntu-latest steps: – name: Checkout code uses: actions/checkout@v2 – name: Run script run: | echo ‘Hello World!’`

Step 2: Configure the Workflow

Once you have created the workflow file, you need to configure the workflow. This includes setting up the triggers, jobs, and actions. To configure the workflow, follow these steps:

1. Define the triggers: Specify the events that will trigger the workflow, such as push or pull requests.
2. Define the jobs: Specify the jobs that will be executed, such as building and testing code.
3. Define the actions: Specify the actions that will be executed, such as running a script or deploying to production.
